My experience was we did not get the VAT returned. Bought an item from Germany for 350 Euro. Received a VAT bill from FedEx. I can't remember the exact amounts. It was under 50.
But long story short..... we returned the item to the company and then I received the bill again from FedEx. Called and explained we return the item but it didn't matter. We were told we could fight the charges but we would have to pay to fight the charges. It ended up being a wash, so just paid the FedEx VAT and learned my lesson.
